Airbnb·Product Manager·Onsite - Product Sense / Strategy

May 2026
Interviewed for a PM role at Airbnb and got a product sense question about dining experiences. Pretty open-ended, which I wasn't fully ready for.
  • How would you improve someone's dining experience?

“I fumbled the opening a bit because I jumped straight into solutions before really scoping the problem.”

Airbnb·Software Engineer·Onsite - System Design / Architecture

May 2026
Airbnb system design round for a software engineer role, basically one long deep-dive into building a distributed key-value store from scratch. The interviewer kept pushing on CAP tradeoffs and I felt like I was treading water by the end of the consistency discussion.
  • Design a distributed key-value store that supports put, get, and delete operations for general-purpose use.
  • How would you handle replication and what consistency guarantees would you expose to clients?
  • Walk me through how your design handles node failures, including temporary and permanent ones.
  • How would you extend this design to support multi-data-center replication?

“I started with the API surface which felt like the right move, laid out put/get/delete and then floated TTL and conditional writes as optional extensions.”

Airbnb·Data Scientist·Technical Phone Screen

May 2026
Airbnb data science interview with a single very deep experimentation question. The whole thing was basically a case study on designing an A/B test for a new Wi-Fi badge feature, and it went several layers deeper than I expected.
  • You work on a two-sided travel search marketplace. Product wants to add a 'High Wi-Fi' badge and filter to help remote workers find listings. Design an experiment to decide whether to launch it, covering randomization strategy, metrics, power analysis, analysis plan, and a dollar-value decision rule.

“This was a monster.”

Airbnb·Software Engineer·Onsite - System Design / Architecture

May 2026
System design round at Airbnb for a software engineer role. The whole thing was one long deep-dive into building a job scheduling platform from scratch, and they kept pushing on the failure handling angle harder than I expected.
  • Design an internal job scheduling platform that supports one-time and recurring jobs, scales to roughly 10 million scheduled jobs, and provides visibility to both job owners and on-call engineers.
  • How do you make the due-job lookup cheap at scale, and what happens when a single minute has an unusually large number of jobs scheduled?
  • How do you ensure exactly one scheduler claims a given job run, and how does the system recover if the claiming scheduler crashes before the job reaches the queue?
  • There's a window between recording a claim in the database and actually publishing the job to the queue. Walk through what can go wrong in each ordering and how you'd make it safe.
  • A worker is mid-execution on a long-running job when its lease expires and the run gets reclaimed. How do you prevent two concurrent executions of the same job?
  • How would you let a team safely cancel a recurring job that already has a run in progress, making sure no already-claimed run still fires after cancellation?
  • What clarifying questions would you ask before designing this system, for example around scheduling granularity, overlap policy for recurring jobs, and missed-run behavior after an outage?

“This was the main question and it ate the whole session.”

Airbnb·Software Engineer·Onsite - System Design / Architecture

May 2026
Airbnb system design round where they asked me to design a retry library from scratch. More open-ended than I expected, less about distributed systems trivia and more about API design philosophy and extensibility thinking.
  • Design a Retryer library that wraps a network operation and retries it on failure. Define the public API, explain the default behavior, describe how callers can customize it, and call out important edge cases.

“This one is sneakily broad.”

Airbnb·Software Engineer·Recruiter / HR Screen

May 2026
Interviewed at Airbnb, just the one question about motivation for joining the company. Not much to report.
  • Why do you want to work at Airbnb?

Airbnb·Software Engineer·Onsite - Behavioral / Leadership

May 2026
Behavioral screen for a software engineer role at Airbnb. The whole thing basically came down to one big motivational question, so if you're not prepped to talk about why Airbnb specifically, you'll feel it.
  • Tell a story about why you want to join Airbnb. How do your motivations connect to the company's mission, and what impact do you hope to make in your first 6 to 12 months?

“This is deceptively hard.”

Airbnb·Product Manager·Onsite - Product Sense / Strategy

May 2026
Airbnb product strategy question about hotels on the platform. Short and focused, probably a screen or early round.
  • How would you shift the way hotels perceive and engage with Airbnb's platform?

“This one took me a second to orient.”

Airbnb·Software Engineer·Onsite - System Design / Architecture

May 2026
Airbnb system design round for a software engineer role. The question was a deep dive into building a watchlist and notification system for rental listings, and it went way further than I expected in terms of breadth.
  • Design a rental listing watchlist and notification system where users can watch a listing for a specific date range, and get notified if a cancellation opens up availability matching their requested dates. Hosts should also be able to see how many users are watching their listing.

“This question has so many layers it's kind of ridiculous.”

Airbnb·Software Engineer·Hiring Manager Screen

May 2026
Interviewed at Airbnb for what seemed like a supply or procurement-adjacent role. Just one question I can remember clearly, and it was pretty open-ended.
  • How do you approach negotiating with vendors?

“I rambled a bit about relationships and leverage without really anchoring it to anything concrete.”
